Jeep’s luxury full-size SUV gains 12 inches: Wagoneer L and Grand Wagoneer L

The new Wagoneer L and Grand Wagoneer L models mean more room to haul more gear.

Jeep puts more wagon and bigger in the Wagoneer and Grand Wagoneer models. Badged ‘L’, the new long-wheelbase offerings will offer segment-leading cargo space as well as more passenger space. The L will also be one of the first vehicles where you can find the powerful new Hurricane straight-six engine.

To make the new models longer, Jeep added 12 inches to the existing Great Wagonnier. However, all that extra length isn’t in the SUV’s tail.

Jeep lengthened the wheelbase by 7 inches and placed the rest of the extra space behind the rear axle. As a result, the L models benefit from a new rear floor, a new rear ladder frame section and some associated chassis modifications with new metal.

Fully boxed frame rails maintain the rigidity of the Wagoneer L and maintain towing and payload capabilities. Aluminum for the hood and doors plus a composite tailgate help keep these workhorses in check – over 6,000 pounds of curb weight! – to weigh even more than them.

Cargo space is extra large


The point of the stretch is, of course, more space. The 44.2 cubic feet of cargo space behind the third row is 50% more than the standard-length model. It’s also just a bit more than the notoriously large former luxury SUV, the Cadillac Escalade ESV and its GMC and Chevy siblings.

With all seats folded down, stretched Jeeps fall short of GM SUV capacity at 130.9 cubic feet. GM inputs manage around 145 when everything is flat. However, Jeeps will still contain a 4 x 8 foot sheet of plywood with room to spare.

When transporting goods that can move, such as camping equipment, coolers, personal watercraft, or anything big or heavy, six tie-down loops help keep everything securely in place. Grand Wagoneer L models are equipped with a rear cargo management rail system to give you even more flexibility.

Plenty of space for up to 8 people

Rear legroom remains class-leading, at least in the second row. There, passengers can find up to 42.7 inches to stretch out. It’s about an inch longer than GM, but it’s the same as standard-length Wagoneers. And 36.6 inches of third-row legroom is a hair’s breadth from best-in-class.

Hurricane I6 makes landfall

Instead of a traditional V8, an all-new twin-turbocharged Hurricane straight-six engine from Stellantis will be standard on the Wagoneer L and Grand Wagoneer L. Wagoneer will use the 420 horsepower, 468 lb-ft of torque, standard-output version. (SW) from I6.

The Grand Wagoneer uses the Hurricane 510, which develops 510 horsepower and 500 lb-ft. SO can use regular gas, but 510 needs at least 91 octane. Both will get the same eight-speed automatic transmission.

Large towing available

With the two new engines, the towing capacity remains exceptional. A two-wheel-drive Wagoneer can handle trailers up to 10,000 pounds. A 4×4 SO tops out at 9,850 pounds, and the high-octane variant is rated up to 9,450. Tow ratings are above the 7,900-pound maximum offered by GM.

The payload, however, is slightly lower. This is something to consider if you are refueling passengers and cargo. The Wagoneer and Grand Wagoneer L range between 1,330 pounds and 1,550 pounds maximum. For reference, GM’s large SUVs range from 1,475 to 1,698 pounds.

Hurricane Fuel Economy

fuel economy ratings for the 4×2 SO are 17 mpg city, 23 highway, or 16/22 with 4×4. The more powerful engine is rated for about 14 city and 19 highway.

The standard Wagoneers without the Hurricanes, meanwhile, don’t do as well. The 5.7L V8 4×4 Wagoneer runs 15/20, the 6.4L V8 Grand Wagoneer 13/19, making the Hurricane a useful upgrade, especially at the pumps. L models also get an extra 4 gallons in their fuel tanks, which means even greater range.

Rear-wheel drive is offered, but expect nearly all of these behemoths to come with one of Jeep’s three 4×4 systems. Quadra-Trac I, Quadra-Trac II and Quadra-Drive II are all on the table.

The first is a permanent system with a limited-slip rear differential. The second is full-time and uses sensors to detect slips. It also has a two-speed transfer case with a low range for off-road adventures.

Third, the Quadra-Drive II with electronic limited-slip rear differential can even anticipate low-traction conditions before the tire hits them.

Jeep Grand Wagoneer L is coming

Look past the longer body and new engines, and it’s the same Jeep Grand Wagoneer and Wagoneer that hit the market last year. The large SUV will offer luxury features that will put it beyond anything Jeep has offered before.

It will also feature technology, including a touchscreen for front passengers. Other off-road perks include a five-level adjustable air suspension that can adjust ride height by up to 8 inches.

When can you expect the Wagoneer L and Grand Wagoneer L? They are ready to arrive Jeep Dealers Later this year. A preview of sorts will come with a very limited run of 2022 model year Grand Wagoneer Hurricane 510 models, available to order now.
